Reading a serial ASCII-encoded string. This sketch demonstrates the Serial parseInt() function. It looks for an ASCII string of comma-separated values. It parses them into ints, and uses those to fade an RGB LED. Circuit: Common-Cathode RGB LED wired like so: * Red anode: digital pin ...

Serial方法是Arduino编程语言中的一个函数,用于与计算机或其他设备进行串行通信。它允许Arduino板与外部设备通过串行通信接口(如USB、UART等)进行数据交换。 Serial方法可以...
Arduino的串口有两类发送的函数Serial.print()类和Serial.write()类,前者以Ascii码的形式将要发送的内容编码发送,所以我们最后接收并看到的是一个一个的ASCII码组合而成的数据,本质上成了字符串;后者则以字节形式直接发送原始数据,所以我们在串口接收工具看到的数据是乱码,它们在计算机中就是这样存储的。
Serial.println(b, DEC) 以十进制形式输出b的ASCII编码值,并同时跟随一个回车和换行符,在测试程序中DEC加与不加效果是完全一样的。 官网对Serial.read()的返回值做出如下介绍:The first byte of incoming serial data available (or -1 if no data is available). Data type: int.,翻译后为:输入的串行数据...
Serial.read(); //读取串口数据 Serial.flush(); //清空串口缓存 Serial.print(); //写入字符串数据到串口 Serial.println(); //写入字符串数据+换行到串口 Serial.write(); //写入二进制数据到串口 Serial.SerialEvent();//read时触发的事件函数 ...
